GM FOOD
GM food is the abbreviation of the genetically—modified food,which is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. GM food has broad prospects in the future.There are many advantages of it.Firstly,it has effective control of insect pests. Crop losses from insect pests can be staggering, resulting in devastating financial loss for farmers and starvation in developing countries. Farmers use many tons of chemical pesticides annually. Consumers do not wish to eat food that has been treated with pesticides because of potential health hazards, and run-off of agricultural wastes from excessive use of pesticides can poison the water supply and cause harm to the environment. Growing GM foods can help eliminate the application of chemical pesticides and reduce the cost of bringing a crop to market.Secondly, it has the good resistance in desease.There are many viruses, fungi and bacteria that cause plant diseases. Plant biologists are working to create plants with genetically-engineered resistance to these diseases so that can solve this problem.Thirdly in the aspect of nutrition,nowadays, rice does not contain adequate amounts of all necessary nutrients to prevent malnutrition. If rice could be genetically engineered to contain additional vitamins and minerals, nutrient deficiencies could be alleviated.
